My bulb in a t8 fixture blew so I ordered an led tube replacement. 6000k, its supposed to be a no rewire just put it in and go bulb. I figured its got to be better than the old t8. Anyone else try these? I have a large full spectrum led for the main light on this tank (110 gallon) and the t8 was fill in for dark areas. Ill post how it works, if anyone want to know.

I would like to see how it works, especially if you can take a photo of it installed. My impression was that you would have to rewire the light fixture to use one of those bulbs, so I hope you double check before trying to just plug and play.

I believe that at least one manufacturer (Phillps) is making direct replacement LEDs for fluorescent tubes. Think about all those commercial buildings with fluorescent fixtures--there is a huge market.

In my basement I had all florescent lighting. About two months ago I bought a 6 pack of of Philips LED replacement tubes. The label claim they are a direct replacement for 40 watt florescent tubes delivering 20% more lumns at only 16 watts of power. But they also clam to be dailight 5.000K spectrum.

As I was putting them in I found that they work as claimed in about half of my fixtures. The single tube fixtures I could not get them to work in. The double tubed ones worked in the fixtures I put in about 8 years ago but did not work in the fixtures that were 20 years old.

They are noticeably brighter than the 34 Watt energy tubes that they replaced. However the old tubes being 6,500K GE bulbs have a noticeable blue compared to these 5,000K bulbs.

ok so I got the tube and installed it. Its a 1 bulb lamp by the way. It lit up for about a minute then went out. Tried to restart it and it would just light breifly. When I contacted the seller he informed me the bulb is not nearly as universal as addvertised. It will only work with a program start ballast. The lowest price one I could find was in the $20.00 range plus $10.00 for the bulb. Way to exspencive for a tired plastic 1 bulb light. So back it goes. Live and learn. It did put out good light though and I may try converting one of my 4 bulb t5 power suckers!

Interesting! I know fluorescent bulbs need a ballast to work at all, and LEDs need a fixed D.C. power supply, so I'm surprised that the LED bulb even lit up. If I wanted to replace a fluorescent bulb with a LED based light I would just strip out the electronic parts of the light fixture, and the sockets, and install a simple 12 VDC power supply and stick lengths of SMD LED tape in the housing. But, I see the need for the bulb type LED lights.

I would be up to replacing a ballast but the 12 volt power supply would be a might over my head. Plus I think the tube led I got was designed to work at florescent tube voltages. Now if you started from scratch with leds maybe. However I got lazy and just bought a new florescent bulb.
